초록

A vacuum transfer system having a weighing hopper mounted via at least one load cell to a frame. The weighing hopper is provided with an inlet connected via a product line to a product inlet hopper and a sliding outlet gate. An actuator valve is operatively connected to the weighing hopper and to a vacuum source. A controller is operatively connected to the actuator valve and also controls the opening and closing of the sliding gate. The product line comprises a flexible pipe section and a rigid pipe section pivotally mounted to the frame at a pivot disp...
